German Type Hose Clamps: Engineered for Performance

German type hose clamps are distinguished by their non-perforated band, which typically features an embossed or wave-like pattern on the underside for grip. This design is often considered to be more robust and gentler on the hose.

Key Features:

Non-Perforated (Embossed) Band: Instead of perforations, the band has a cold-formed thread profile on the outside and is smooth or has a wave-like pattern on the inside. This design is believed to provide more uniform pressure distribution and reduce the risk of hose damage, especially on softer hoses.

Asymmetrical Housing: The housing for the screw mechanism is often asymmetrically designed. This can provide a more direct and efficient transfer of force from the screw to the band, leading to higher and more consistent clamping force.

Smooth Band Underside: The smooth interior surface of the band minimizes pinching, cutting, or extruding of the hose material as the clamp is tightened.

Screw Type: Usually features a 7mm hex head, sometimes with a slot.

Material: Predominantly manufactured from high-quality stainless steel (often designated by "W" grades, such as W2, W4, W5, indicating varying levels of corrosion resistance and material composition of band, screw, and housing).

Higher Clamping Force: Generally capable of achieving higher and more evenly distributed clamping forces compared to American types, making them suitable for higher pressure applications.
